This new international journal consolidates research activities in chemistry physics and technology of porphyrins and phthalocyanines into a single unique and easily accessible reference source. JPP provides the means for researchers scientists and engineers interested in exploring the applications of these materials to publish original research papers and short communications. As well as reviewing state-of-the-art topics up-to-date research news and patent reports the journal features an up-to-date calendar of events and a running list of published papers and authors. JPP is an international peer-reviewed journal for the fast refereeing and publication of articles. The journal includes the following subjects: Synthesis Chemical syntheses of porphyrins phthalocyanines structurally related macrocycles such as porphyrazines corroles chlorins porphycenes porphyrinogens subphthalocyanines porphocyanines heterocyclic analogues related expanded -conjugated macrocycles their oligomers polymers copolymers composites and blends molecular design coordination chemistry kinetics and reaction mechanisms and biosynthesis.
