In recent years, significant strides to enhance the functionality and adaptability of devices have been taken in the field of optoelectronics. Now, a team of scientists from State Key Laboratory of Supramolecular Structure and Materials, College of Chemistry, Jilin University, have reported a breakthrough in the development of organic flexible optoelectronic devices using acicular organic crystals.

The crystals, which range from micro- to centimeter-scale in length, have been used as media for transducing optical signals, functioning as active or passive optical waveguides. By integrating the dynamic adaptability of crystals with optical waveguides, the researchers have opened new possibilities for creating crystal-based devices.

“We introduced a Schiff base crystal with remarkable properties, including integrated elastic-bending, plastic-twisting, and acid-bending deformations, alongside protonation-induced crystal acidichromism,” said Hongyu Zhang, corresponding author of the study.

“This unique combination allows the emission ****** of a single crystal to be selectively and reversibly controlled, varying between green (554 nm) and deep red (659 nm) when exposed to protonic acid vapor. This ****** change creates various block heterojunction structures that can be easily identified by their distinct colors and emissions.”

The researchers emphasized that the Schiff base they prepared combines multiple flexibilities and optical output tunability. The crystals exhibit excellent bending elasticity and twisting plasticity, which can be independently controlled.

“Notably, the heterojunction structures, formed through partial acid-fuming of slender crystals, display an erasing-rewriting feature, allowing for the reconfigurable regulation of emission outputs,” adds Zhang. “This reconfiguration capability enhances the practicality of the crystals in developing flexible optical tuners with a wide range of adjustable output signals.”

The compatibility of the crystals’ mechanical properties and acidichromism further enhance their functionality. The study’s results,
