The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) IF: 0.7 To calculate the five year Impact Factor, citations are counted in 2017 to the previous five years and divided by the source items published in the previous five years. 2017 Journal Citation Reports (Clarivate Analytics, 2018) 5-Year IF: 0.7 The Immediacy Index is the average number of times an article is cited in the year it is published. The journal Immediacy Index indicates how quickly articles in a journal are cited. Immediacy Index: 0.1 The Eigenfactor score, developed by Jevin West and Carl Bergstrom at the University of Washington, is a rating of the total importance of a scientific journal. Journals are rated according to the number of incoming citations, with citations from highly ranked journals weighted to make a larger contribution to the eigenfactor than those from poorly ranked journals. Eigenfactor: 0.00016 The Journal Citation Indicator (JCI) is a single measurement of the field-normalized citation impact of journals in the Web of Science Core Collection across disciplines. The key words here are that the metric is normalized and cross-disciplinary. JCI: 0.18 SJR: 0.313 SNIP: 0.6 CiteScore™:: 1.6 H-Index: 16

RESUMO

2,4,6-Trinitrotoluene (TNT) is a well-known military explosive. For chemists, however, TNT represents a polyfunctional molecule that could serve as a source for various higher value products. We have systematically investigated numerous chemical transformations of TNT with the goal of producing useful materials for civilian applications. We have developed techniques for the selective conversion of the nitro and methyl groups in TNT, which has allowed the subsequent production of new high performance polymers.
We initially converted TNT to 1,3,5-trinitrobenzene (TNB). TNB was then transformed into a variety of dinitro-and diaminoarenes containing phenoxy, thiophenoxy, phenylsulfoxide and phenylsulfone substituents. The substituted dinitroarenes were used for the preparation of aromatic polyethers. The substituted diaminoarenes were used for the preparation of aromatic polyamides and polyimides having improved processibilities combined with good thermal and mechanical properties.
