Synthesis, Structure, and Large Optical Limiting Effect of the First Coordination Polymeric Cluster Based on an {I@[AgI(inh)]6} Hexagram Block
摘要:
In this paper, treatment of N-(isonicotinoyl)-N'-nicotinoylhydrazine (inh) and Agl with excess KI afforded a unique coordination polymeric cluster {[Agl(inh)](6)(KI)}(n) (1) with the hexagram cluster units centered by mu(6)-l. In the polymer these hexagram units are parallel to the ab plane and are linked by separated K+ centers through inh. Polymer 1 represents the first example of coinstantaneous cation-anion-induced supramolecular self-assembly with nanoscale inner cavities. The polymer's third-order nonlinear optical (NLO) properties were determined by the Z-scan technique in DMF solution. The results show that the polymer has strong third-order optical nonlinearities. The nonlinear absorptive index a(2) and refractive index n(2) are calculated to be 1.044 x 10(-9) mW(-1) and 2.827 x 10(-11) esu, respectively. The values are comparable to those of the reported cluster polymers. The optical limiting experiments show that the present cluster exhibits a large optical limiting capacity. The value of the limiting threshold was measured as 0.53 J cm(-2) from the optical limiting experimental data. This value is three times better than 1.6 J cm(-2) of C-60. This paper also gives a summary and comparison on the optical limiting properties of oligomeric and polymeric clusters.

Inhibitors of microbial heme oxygenase and their use for treatment of microbial infections and bioremediation. The inhibitors of microbial heme oxygenase are useful against a new class of antimicrobial agents to target infections that are persistently difficult to combat with the current spectrum of antimicrobial agents. Screening methods for selecting inhibitors of microbial heme oxygenase.
