  Cyclo-oligomerization of 6,12-Diethynyl Indeno[1,2-b]fluorenes via Diradical Intermediates

  摘要：

  Indeno[1,2-b]fluorene derivatives with trimethlysilylethynyl substituents at the 6- and 12-positions were found to undergo cyclo-dimeerzatin cyclo-trimaerzatio and higher oligomerization at room tempeatrue. The cyclic dimer feature a novel double-decker motif, composed of two face-to-face stacked bis(propadienylide)dihydroindeno[1,2-b] flourenes with a short centroid-to- centroid distance of 3.50 angstrom. The existence of a cyclic timer and higher oligemers was indeno[1,2-b]fluorene moiety.

  日期：2020.5

  exhibit a praiseworthy electrochromism, to be specific, with vivid colors, high optical contrast, fast response and excellent durability. To our surprise, one phthalate with the methoxyl substituent reveals an unanticipated photoluminescent nature, which renders the compound multifunction. In summary, outstanding electrochromic performances indicate that these phthalate derivatives are promising for applications

  An emerging strategy to enable energy efficient gas storage and separation technologies is the development of stimuli-responsive physisorbents. Herein, we report two isostructural light-modulated adsorbents (LMAs) which undergo pressure-induced transformations from closed (non-porous) to open (porous) phases via adsorption of N2, CO2 and C2H2.

• Coplanarity in the Backbones of Ladder-type Oligo(<i>p</i>-phenylene) Homologues and Derivatives

  p-Tolyl-substituted ladder-type oligo(p-phenylene) s containing three, four, and five phenylene rings were readily synthesized. The uniform aryl substitution of these systems allowed us to determine the coplanarity of the d-conjugated backbones crystallographically. The intramolecular annulations eliminate almost all of the conformational disorder and enhance the degree of d-conjugation of the backbones, resulting in significant red shifts in the absorption and emission maxima and lower oxidation potentials in the higher homologues.
