Based on the three-dimensional nuclear independent chemical shielding（3 D-NICS） theory,a new program was coded at the end of *** early 2017,this program is firstly used to calculate the aromatic/anti-aromatic transferring mechanism in a newly-prepared sandwich rare earth *** the experiment,two mixed（phthalocyaninato）（hemiporphyrazinato） and two homoleptic bis（hemiporphyrazinato） rare earth double-decker complexes have been synthesized and structurally *** EPR and NMR results clarified the protonated nature of these sandwich *** and theoretical calculation results clearly reveal the predominantly aromatic nature of the mixed ring sandwich double-deckers.

RLINl,encoding a putative coproporphyrinogen Ⅲ oxidase,is involved in lesion initiation in rice

Lesion mimic is necrotic lesions on plant leaf or stem in the absence of pathogenic infection, and its exact biological mechanism is varied. By a large-scale screening of our T-DNA mutant population, we identified a mutant rice lesion initiation 1 （rlin1）, which was controlled by a single nuclear recessive gene. Map-based cloning revealed that RLIN1 encoded a putative coproporphyrinogen Ⅲ oxidase in tetrapyrrole biosynthesis pathway. Sequencing results showed that a G to T substitution occurred in the second exon of RLIN1 and led to a missense mutation from Asp to Tyr. Ectopic expression of RLIN1 could rescue rlin1 lesion mimic phenotype. Histochemical analysis demonstrated that lesion formation in rlin1 was light-dependent accompanied by reactive oxygen species accumulated. These results suggest that tetrapyrrole participates in lesion formation in rice.

Optically active binaphthyl units have been introduced onto the periphery of the phthalocyanine chormophores in the phthalocyanine-porphyrin-fused oligomers,resulting in the first（R）-and（S）-enantiomers of Pc-Por-fused dimer and trimer with induced chirality *** represents the largest chiral tetrapyrrole-based conjugated system,to the best of our *** absorption,MCD,and CD spectroscopic results in combination with theoretical calculations disclose the effective transfer of the chiral information from the binaphthyl groups to both the central tetrapyrrole-fused chromophores,indicating the effective delocalization of the π-electron density over the fused systems due to the effective electronic communication between/among the tetrapyrrole chromophores.
