  Chiral Memory Units Based on Dynamic Redox Systems with a Dibenzoxepinone Skeleton: Drastic Change in Racemization Barrier and Electrochemical Bistability

  摘要：

  The configuration of helical dicationic dyes 2(2+) with a dihydrodibenzoxepinone unit is stable, whereas the corresponding neutral electron donors 1 with a tetrahydrophenanthroxepinone skeleton easily undergo ring-flip. Thanks to their electrochemical bistability, electron exchange between 1 and 2(2+) is prohibited. Thus, the above electrochromic pairs 1/2(2+) can serve as new members of less well-explored redox-based chiral-memory units.

• Geometrical Remote Steric Effects in 4,5-Disubstituted-9,10-dihydrophenanthrenes: Expansion of Prestrained C⁹–C¹⁰ Bond in Di(spiroacridan) Derivatives

  By attaching bulky substituents at the bay region of di(spiroacridan)-substituted dihydrophenanthrene 1a, the prestrained C9–C10 bond in the dihydrophenanthrene (DHP) skeleton of 1c–1e is expanded from 1.634(2) to 1.649(3)–1.652(6) Å, which demonstrates the bond expansion through remote steric effects. Twisting deformation of the DHP skeleton is the key to transfer the steric bulkiness from the C4/C5 positions to cause the additional strain in the C9–C10 bond.

  通过在二（螺吖啶）取代的二氢菲1a的湾区域附加庞大的取代基，1c-1e的二氢菲（DHP）骨架中的预应变C9-C10键从1.634(2)扩展到1.649(3)-1.652(6) Å，这表明了通过远端立体效应实现的键扩展。DHP骨架的扭曲变形是将C4/C5位置的庞大体积转移到C9-C10键上产生额外应变的关键。

  Acridine-based novel fluorophores 1/2 with a helical dihydrodibenzoxepin/azepine skeleton exhibit halochromic response upon addition of Brønsted acid in CH2Cl2, thus giving UV–vis and fluorescence spectral changes. By using the optically resolved species [(M)-1/2], circular dichroism (CD) and fluorescence detected-CD (FDCD) signals were also changed drastically, thus demonstrating four-way-output response thanks to configurational stability of helicity and efficient exciton coupling.

  The title dication (1(2+)) was generated by oxidative bond cleavage of a 4,5-dihydoropyrene derivative (2) with two spiro(10-methylacridan) units. Despite the skewed deformation of the arylene spacer, two cationic chromophores in 1(2+) are forced to face in a proximity with a very short interatomic separation of 2.98(1) angstrom between carbenium centers (X-ray), which makes the LUMO level of 1 much lower than that of biphenyl-2,2'-diyl-type dication (3(2+)).
