To provide a photosensitive composition with which it is possible to form partition walls (black matrix) having excellent light shielding properties and liquid repellency.
A photosensitive composition, which comprises a polymer (A) having a side chain containing a fluorine atom-containing group or a silicon atom-containing group and a side chain containing an ethylenic double bond in one molecule, a black colorant (B), a photopolymerization initiator (C) which is an O-acyloxime compound, and a photosensitive resin (D) containing an acidic group and an ethylenic double bond in one molecule, wherein the proportion of the black colorant (B) in the total solid content of the composition is from 15 to 60 mass %.

Optically Pure <i>C</i><sub>1</sub>-Symmetric Cyclic(alkyl)(amino)carbene Ruthenium Complexes for Asymmetric Olefin Metathesis
An expedient access to the first optically pure ruthenium complexes containing C1-symmetric cyclic (alkyl)(amino)carbene ligands is reported. They demonstrate excellent catalytic performances in asymmetric olefinmetathesis with high enantioselectivities (up to 92% ee). Preliminary mechanistic insights provided by density functional theory models highlight the origin of the enantioselectivity.

application of a dehydrogenase from this Sulfolobus hyperthermophile to asymmetric synthesis and the first example of a DYRKR with such an enzyme. The requisite aldehydes are generated by Buchwald−Hartwig-type Pd(0)-mediated α-arylation of tert-butyl propionate. This is followed by reduction to the aldehyde in one [lithium diisobutyl tert-butoxyaluminum hydride (LDBBA)] or two steps [LAH/Dess−Martin
