英文摘要	The present article investigates a reversible structural phase transition, and related physical properties change in a new quasi-one-dimensional (1D) organic semiconductor crystal, DBA(TCNQ)(2) [DBA = dibutylammonium, TCNQ = 7,7,8,8-tetracyanoquinodimethane]. Differential scanning calorimetry traces reveal the DBA(TCNQ)(2) single crystal undergoes a first-order reversible phase transition at around 260-270 K, which is accompanied by a dramatic change in both conductivity and magnetic susceptibility. A direct correlation of physical properties with crystal structure is established. Detailed X-ray structure analyses indicate a reversible structural change related to dimer-tetramer transition along the TCNQ chain and disruption of the hydrogen-bonding chains as the temperature decreases from 270 to 253 K, which is the origin of the electronic and magnetic. transition.; Chemistry, Physical; Nanoscience & Nanotechnology; Materials Science, Multidisciplinary; SCI(E); EI; 10; ARTICLE; 29; 11001-11006; 112
