Red-shifting the absorption of norbornadienes (NBDs), into the visible region, enables the photo-isomerization of NBDs to quadricyclanes (QCs) to be driven by sunlight. This is necessary in order to utilize the NBD–QC system for molecular solar thermal (MOST) energy storage. Reported here is a study on five diaryl-substituted norbornadienes. The introduced aryl-groups induce a significant red-shift of the UV/vis absorption spectrum of the norbornadienes, and device experiments using a solar-simulator set-up demonstrate the potential use of these compounds for MOST energy storage.
将降冰片二烯(NBDs)的吸收红移到可见光区域,可使 NBDs 在阳光的驱动下光异构化为四环(QCs)。这对于利用 NBD-QC 系统进行分子太阳能热(MOST)储能是非常必要的。本文报告了对五种二芳基取代的降冰片二烯的研究。引入的芳基使降冰片二烯的紫外/可见吸收光谱发生了显著的红移,使用太阳能模拟装置进行的设备实验证明了这些化合物用于 MOST 储能的潜力。
