Article Synopsis
- The performance of crystalline organic semiconductors is significantly influenced by their solid-state structure, particularly how the conjugated components are oriented in relation to device platforms.
- Engineering crystal orientation through chromophore modification is challenging, as traditional processing techniques provide limited control over this aspect.
- Crystal twisting has emerged as a novel method that enhances the properties of organic semiconductors, enabling the introduction of chiral characteristics and improving performance in applications like chiral sensing and optical telecommunications.
Tetrathiafulvalene (TTF) crystals grown from the melt are organized as spherulites in which helicoidal fibrils growing radially from the nucleation center twist in concert with one another. Alternating bright and dark concentric bands are apparent when films are viewed between crossed polarizers, indicating an alternating pattern of crystallographic faces exposed at the film surface. Band-dependent reorganization of the TTF crystals was observed during exposure to methanol vapor.
