Structural tunning of hydrogen-bonded motifs in response of an external stimuli to form 2D-sheet and 3D-HOFs from 1D-chain in the solid-state

Abstract

Molecules in their solid state are tightly packed through various modes of interaction, and their crystal forms are highly fragile in response to external stimuli/disturbance, especially if they are connected through weak hydrogen bonds. In this presentation, we are going to highlight the transformation of anion-templated hydrogen-bonded 1D motifs to 2D-sheet1 and 3D-HOFs², respectively, in response to an external stimulus such as light and heat. During this transformation, molecule covers a remarkable distance in their corresponding crystal forms, stabilized by anion•••π interactions. In this presentation, we will discuss the complete process with mechanistic studies.
