Bulk Assembly of Organic Metal Halide Nanoribbons [PDF]

Chem. Commun. 59, 3711-3714 (2023), 2022
Organic metal halide hybrids with low-dimensional structures at the molecular level have received great attention recently for their exceptional structural tunability and unique photophysical properties. Here we report for the first time the synthesis and characterization of a one-dimensional (1D) organic metal halide hybrid material, which contains ...
