Flexible Organic Charge-Transfer Cocrystals with Near-Infrared Emission.

ABSTRACT: Flexible organic crystals have been recently explored for optical transduction in flexible small-scale optical devices; however, most studies are limited to the visible range (400-600 nm). Due to the photonic well confinement and low optical losses, optical telecommunications require transducive media with tunable optical emission in the 850-1550 nm region. While chemical substitution is a viable option to shift the emissive properties of organic crystals to the telecom regime, depending on the target modification, this could be a resource-intensive approach. Here, with two cocrystals of 1,1'-biphenyl (BP), 4,4'-dimethylbiphenyl (DM), and 7,7,8,8-tetracyanoquinodimethane (TCNQ), we demonstrate that cocrystallization provides an alternative and straightforward access to organic materials wi
