Light-responsive molecular systems with multiple photoswitches in C3-symmetric designs have enormous application potential. The design part of such molecular systems is critical due to its influence in several properties associated with the photoswitches. In order to tune, and in the evaluation of the design–property relationship, we synthesized 18 tripodal systems with variations in the core, linkers, connectivity, and azo(hetero)arene photoswitches. Through extensive spectroscopic and computational studies, we envisaged the factors controlling near-quantitative photoisomerization in both the directions (bistability) and the thermal stability of the metastable states. Furthermore, we also evaluated the impact of designs in obtaining reversible photo-responsive sol-gel phase transitions, solvatochromism, photo- and thermochromism.

The synthesis and complexing properties of p-aminoazobenzene-derived mono-, bis-, and trisamides were described. Ligands 3 and 4 bind anions, including fluorides, chlorides, bromides, acetates, benzoates, dihydrogen phosphates, hydrogen sulfates, and p-to
Microwave-assisted synthesis of amides from various amines and benzoyl chloride under solvent-free conditions: A rapid and efficient method for selective protection of diverse amines

A number of structurally diverse amides were synthesized by reaction of the corresponding amines with benzoyl chloride under microwave irradiation. The proposed procedure ensures short reaction time, high yields, and excellent selectivity and considerably broadens the series of amines as compared to the microwave-assisted synthesis of amides directly from carboxylic acids. It can also be used for selective protection of various amines, including aromatic, aliphatic, and heterocyclic.
