Twist and shout: The synthesis of polyfunctional thiophenes is reported. Quantum-mechanical calculations explain the synthetic pathway of this heterocyclization. Both experimental and computational spectral results demonstrate that the optical properties of the synthesized thiophenes are caused by the presence of an intramolecular charge-transfer (ICT) state during absorption and a twisted ICT state
捻转:报道了多官能噻吩的合成。量子力学计算解释了这种杂环化的合成途径。实验和计算光谱结果均表明,合成的噻吩的光学性质是由吸收过程中分子内电荷转移(ICT)状态的存在和激发态中几何弛豫后的扭曲ICT状态引起的。
