Compounds that are suitable to be used for three-dimensional optical recording materials, etc. The compounds each have a structure that allows pi-electron conjugation to be achieved by linking a porphyrin ring and a perinaphthothioindigo ring to each other with a straight-chain atomic group. The compounds of the present invention are suitable to be used for three-dimensional optical recording materials, etc. since they have a high two-photon absorption efficiency and undergo photochromism effectively through optical absorption.
A novel heterocyclic compound is provided. In particular, a novel heterocyclic compound which can improve the element characteristics of a light-emitting element is provided. A novel light-emitting element with high emission efficiency and high heat resistance is provided. A heterocyclic compound represented by General Formula (G1). A represents any of a dibenzothiophenyl group, a dibenzofuranyl group, and a carbazolyl group. DBq represents a dibenzo[f,h]quinoxalinyl group. In addition, n is 0 or 1. Each of Ar1 to Ar4 independently represents a substituted or unsubstituted arylene group having 6 to 10 carbon atoms. In Ar1 to Ar4, the adjacent arylene groups may be bonded to each other to form a ring. When the adjacent arylene groups in Ar1 to Ar4 form a fluorene skeleton, the fluorene skeleton may have a substituent.

This disclosure relates to a composition for use as an additive for fuels and lubricants including a reductive amination product of a vinyl terminated macromonomer (VTM) based aldehyde. Optionally aldehyde is reacted with the amino compound under condensation conditions sufficient to give an imine intermediate, and the imine intermediate is reacted under hydrogenation conditions sufficient to give the composition. The aldehyde is formed by reacting a VTM under hydroformylation conditions sufficient to form the aldehyde. A reductive amination method for making a composition for use as an additive for fuels and lubricants. The method includes reacting a VTM based aldehyde with an amino compound containing at least one —NH— group under condensation conditions sufficient to give an imine intermediate, and reacting the imine intermediate under hydrogenation conditions sufficient to give said composition. The aldehyde is formed by reacting a VTM under hydroformylation conditions sufficient to form the aldehyde.
