SYNTHESIS AND SELF-ASSEMBLY OF CARBOHYDRATE NAPHTHALIMIDE SCAFFOLDS FOR ELECTRONIC APPLICATIONS

Abstract

A series of carbohydrate naphthalimide derivatives were synthesized in good yields using environmentally benign protocols. Self-assembly studies revealed that most of the synthesized compounds were able to form a gel in a diverse range of solvents and oils. Self-assembled carbohydrate naphthalimides were employed to develop flexible semiconductors and triboelectric nanogenerators (TENG). The fabricated TENG was used to construct self-powered electronics, humidity sensors, and the electrochemical system. It is worth mentioning that one of the fabricated TENG using self-assembled carbohydrate naphthalimide derivatives rendered a power density of 18.96 W/m2. A small tuning of the molecular structure of assembled materials could bring big implications in electronics.
