Aromatic amines were reported to show visible light absorption by the adsorption on TiO2 nanoparticles, enabling visible light responsive photocatalytic reactions. However, the origin of the visible light absorption and the chemisorption structure have not been elucidated in detail yet. Here, we demonstrate experimentally and computationally that the visible light absorption in the TiO2-indole surface complex is attributed to interfacial charge-transfer transitions (ICTT) from the adsorbed indole to TiO2, supporting the chemisorption structure of indole via a Ti-N bond formed by the dehydration reaction with a surface hydroxy group. The ICTT originates from pi(indole)-d(pi)(Ti) electronic couplings through the Ti-N bond.

The first solvent-mediated tunable C3/C7 regio- and enantioselective Friedel-Crafts alkylation of 4-aminoindoles with alpha-ketimino esters has been developed. This catalysis allows the highly regioselective formation of indole C3 and C7 alkylation products, both in high yields (up to 96%) and excellent enantioselectivities (up to 99% ee). Mechanism study revealed that the hydrogen-bonding interactions of the solvents with the catalyst played a vital role for the regioselectivity switch. Furthermore, the corresponding products are indole containing unnatural alpha-amino acid derivatives bearing a quaternary stereocenter and enable many further elaborations.

An effective protocol for the plant regeneration via direct and indirect organogenesis has been developed from leaf explants of Asystasia gangetica (L.), cultured on Murashige and Skoog (MS) medium supplemented with various concentrations and combinations of auxin and cytokinins. Approximately 86% of explants produced direct shoots on MS medium containing 0.5 mg L-1 6-benzyladenine (BA) and 10 mu g L-1 Triacontanol (TRIA) with a maximum of 4.82 +/- 0.29 shoots per leaf segment. For production of callus-mediated plantlets (indirect), primarily callus was induced on MS medium containing 2 mg L-1 2,4-dichlorophenoxyacetic acid (2,4-D), which was then subcultured on medium with 0.1 mg L-1 naphthaleneacetic acid (NAA), 0.5 mg L-1 BA, and 1 to 8 mg L-1 2-isopentenyl adenine (2iP) in order to develop organogenic callus and subsequent shoot induction. A maximum of 6.84 +/- 0.05 shoots per callus clump was obtained on MS media supplemented with 4 mg L-1 2iP, 0.5 mg L-1 BA, and 0.1 mg L-1 NAA. The shootlets produced roots when cultured on half-strength MS media supplemented with 2 mg L-1 indole-3-butyric acid (IBA). In vitro propagated plantlets were hardened on soil rite and acclimatized to field condition with 85% survivability. The chlorophyll content of acclimatized plants was comparable with that of the mother plant, while stomatal micromorphology of regenerated plants exhibited no abnormalities. The radical scavenging and antioxidant activity of methanolic extract of leaves were measured by 2,2-diphenyl-1-picrylhydrazyl (DPPH), ferric reducing ability of plasma (FRAP), and phosphomolybdenum test. In all experiments, regenerated plants exhibited enhanced antioxidant potential indicating micropropagated plants could be exploited for isolation of novel biomolecules. Further, the genetic homogeneity of acclimatized plants was confirmed by PCR-based start codon targeted (SCoT) markers and ycf1b DNA barcoding primers which exhibited monomorphic bands identical to the normal mother plant and no variations were observed.

The adsorption capacities of two synthesized zeolites (crystalline ZSM-5 and semi-crystalline faujasite Y) for a mixture of indole, quinoline and carbazole were studied. The different samples obtained show different crystalline degree, mesoporosity and Si/Al ratios. The synthesis procedure is based on the simultaneous depolymerization of a mixture of high surface area silica, such as rice hull ashes (RHA), and a crystalline zeolite, such as clinoptilolite or faujasite. The depolymerization step is followed by a partial reorganization induced by a structure-directing agent. A model mixture of nitrogenous compounds was prepared, then it was mixed with the zeolite samples and the amount adsorbed of nitrogenous compounds was determined by gas chromatography. Analysis of the adsorbed molecules reveals selectivity in favor of quinoline, followed by indole and then carbazole. The best adsorbent properties correspond to the solid with highest porous volume. The samples obtained were characterized by X-ray diffraction, Si-29 and Al-27 magic-angle spinning nuclear magnetic resonance, X-ray fluorescence and Fourier transform infrared spectroscopy. The Barrett-Joyner-Halenda (BJH) pore size distribution and the Brunauer-Emmet-Teller (BET) surface area values were obtained from N-2 adsorption/desorption isotherms.
