The synthesis of five homoleptic transitionmetal complexes of bis-(phenyl)-diisoindol-aza-methene is described together with the optical, electrochemical and thermal properties of these compounds. Additionally, crystalstructures for the Co and the Zn complex are reported.

A parameter is reported by which to use 13C NMR chemical shifts to measure and predict the donor capabilities of N^N dipyrrinato and aza-dipyrrinato ligands chelating in L^X fashion. The results enable the rationalisation of the properties of these ligands and their complexes, as well as enable rational design incorporating both steric and electronic considerations when tuning to effect desired applications
报道了使用13 C NMR化学位移来测量和预测以L X方式螯合的N 2 N二吡喃酮和氮杂二吡喃酮配体的供体能力的参数。结果使得这些配体及其配合物的性质合理化,并且使得在进行调谐以实现所需的应用时能够合理地设计并结合了空间和电子方面的考虑。含有这些配体的配合物是普遍存在的,因为它们具有所需的光物理性质,例如高化学稳定性,耐光降解性,强吸收性和易于化学修饰性。
Synthesis and Characterization of Near-Infrared Absorbing Benzannulated Aza-BODIPY Dyes
synthesized by the addition of aryl Grignardcompounds to phthalodinitrile and subsequent reaction with formamide. A plausible reactionmechanism, through a Leuckart–Wallach‐type reduction has been confirmed by means of DFT calculations of the related transition and intermediate states. The corresponding boron difluoride complexes (10) of 9 were prepared in a subsequent reaction step and the spectroscopic and

phthalonitrile-based electrophile with a Grignard reagent followed by reduction with formamide at high temperature. In this work, we introduce a new fused-ring aza-dipyrromethene synthesis from ortho-lithiated aromaticnitriles. This method allows for a much wider range of functional groups, less complicated starting materials, and yields that are consistent with the highest reported for aza-dipyrromethenes of any kind
Fusion of benzene moieties onto the BODIPY periphery in combination with the introduction of peripheral chiral binaphthyl substituents renders the extension of optical activity of resulting chiral benzo-fused aza-BODIPYs into the near-IR (NIR) range, representing the first chiral BODIPYs with NIR optically activity. For comparative study, N,N-difluoroboryl-[N-(3-phenyl-2H-isoindol-1-yl)-N-(3-phenyl-1
