Transfer of Chiral Information from Silica Hosts to Achiral Luminescent Guests: a Simple Approach to Accessing Circularly Polarized Luminescent Systems

Seiji Tsunega, +3 more
- 01 Apr 2020 - 
TL;DR: This work proposes inorganic-based CPL-active systems constructed by the "chiral host-luminescent guest" strategy, in which silica acts as a chiral host to endow various luminescent guests with CPL.
Journal ArticleDOI

Preparation and acid-responsive photophysical properties of T-shaped π-conjugated molecules containing a benzimidazole junction.

Toshifumi Inouchi, +3 more
- 04 Nov 2011 - 
TL;DR: The π-conjugated molecule with ethynyl spacers exhibited a marked redshift in the fluorescence spectrum with a large Stokes shift upon the addition of acid, whereas the other molecules showed substantial quenching, which indicated the transition to a CT state over the finite activation energy at the excited state.
Journal ArticleDOI

Photoluminescence Quenching in Polysilanes by Fullerene Doping and Effective Photoinduced Charge Transfer Depending on Aromatic Side Group

Katsumi Yoshino, +7 more
- 01 Jan 1995 - 
TL;DR: In this paper, the role of the aromatic side group as a mediator for photoinduced electron transfer from electronic states of the main chain polysilanes to the C60 molecule was investigated.
Journal ArticleDOI

Photoinduced Solubilization of Conducting Polymer and Its Application to Etching and Recording

Katsumi Yoshino, +4 more
- 20 Sep 1990 - 
TL;DR: In this paper, the authors proposed that nonsoluble parts of conducting poly(3-alkylthiophene) become soluble into organic solvents upon irradiation of light of photon energy larger than the band gap.
Journal ArticleDOI

Synthesis and photochromic properties of a dithiazolylindole

Sayo Fukumoto, +2 more
- 01 Feb 2012 - 
TL;DR: In this paper, a novel photochromic 2,3-dithiazolylindole has been synthesized and its photo-chromic properties were elucidated, showing reversible photochromism both in solution and in a crystal with no spontaneous bleaching under dark conditions.
