Triphenylene can be isolated from coal tar , but it is also made synthetically using benzyne chemistry. One molecule of triphenylene has delocalized 18 electron systems based on a planar structure. It has the molecular formula chem C 18 H 12 . Triphenylene is a fully benzenoid PAH, meaning its structure is composed only of full benzene rings interconnected by carbon carbon single bonds. The three benzene rings can be drawn as the three outer rings, with the central ring formed by one face of each and the three carbon carbon single bonds. Being a fully bezenoid PAH means that triphenylene is much more Resonance chemistry resonance stable than its isomers chrysene , benz a anthracene benz a anthracene , benzo c phenanthrene benzo c phenanthrene , and tetracene . This makes it much more difficult to hydrogenate to the saturated hydrocarbon . In light of these characteristics, triphenylene may have uses in optics and electronics .

enzyme Name salicylaldehyde dehydrogenase EC number 1.2.1.65 CAS number IUBMB EC number 1 2 1 65 GO code 0018485 image width caption In enzymology , a salicylaldehyde dehydrogenase EC number 1.2.1.65 is an enzyme that catalysis catalyzes the chemical reaction salicylaldehyde NAD sup sup H sub 2 sub O math rightleftharpoons math salicylate NADH 2 H sup sup The 3 substrate biochemistry substrates of this enzyme are salicylaldehyde , nicotinamide adenine dinucleotide NAD sup sup , and water H sub 2 sub O , whereas its 3 product chemistry products are salicylate , nicotinamide adenine dinucleotide NADH , and hydrogen ion H sup sup . This enzyme belongs to the family of oxidoreductase s, specifically those acting on the aldehyde or oxo group of donor with NAD or NADP as acceptor. The systematic name of this enzyme class is salicylaldehyde NAD oxidoreductase . This enzyme participates in naphthalene and anthracene degradation.

enzyme Name cis 1,2 dihydro 1,2 dihydroxynaphthalene dehydrogenase EC number 1.3.1.29 CAS number 53986 49 5 IUBMB EC number 1 3 1 29 GO code 0018505 image width caption In enzymology , a cis 1,2 dihydro 1,2 dihydroxynaphthalene dehydrogenase EC number 1.3.1.29 is an enzyme that catalysis catalyzes the chemical reaction cis 1,2 dihydronaphthalene 1,2 diol NAD sup sup math rightleftharpoons math naphthalene 1,2 diol NADH H sup sup Thus, the two substrate biochemistry substrates of this enzyme are cis 1,2 dihydronaphthalene 1,2 diol and nicotinamide adenine dinucleotide NAD sup sup , whereas its 3 product chemistry products are naphthalene 1,2 diol , nicotinamide adenine dinucleotide NADH , and hydrogen ion H sup sup . This enzyme belongs to the family of oxidoreductase s, specifically those acting on the CH CH group of donor with NAD or NADP as acceptor. The systematic name of this enzyme class is cis 1,2 dihydronaphthalene 1,2 diol NAD 1,2 oxidoreductase . Other names in common use include cis naphthalene dihydrodiol dehydrogenase , naphthalene dihydrodiol dehydrogenase , and cis dihydrodiol naphthalene dehydrogenase . This enzyme participates in 1 and 2 methylnaphthalene degradation and naphthalene and anthracene degradation .
