“…[2] Aniline has a long and rich scientific and technological history, [1] first as a dyestuff (i.e., so-called aniline black [3] ) and, more recently, as the basis for molecular- [4] and macromolecular-based [5] functional organic materials. Yet, despite being one of the most studied classes of conducting organic materials to date, its recent scientific development has been surprisingly erratic.…”

The simple and elegant Buchwald-Hartwig cross-coupling reaction has been used to synthesise a designed range of new aniline-based tetramers in one step, and without the need for protecting groups. Variation of the central aromatic ring has provided the opportunity to carefully tune the optoelectronic properties in this series, thus enabling a structure-activity relationship study by using a range of photophysical and electrochemical techniques. As a result, the long-proposed sequences of electron-electron (EE) and electron-chemical (EC) processes that support the complex redox and proton-transfer reactions involved in the well-known switching of redox states of poly- and oligo(aniline)s are revealed here for the first time. We also present the initial results from time-dependent DFT calculations to clarify the optoelectronic behaviour of these oligomers. The dc-conductivity measurements of conducting thin films of this series, doped with the prototypical poly(aniline) protonating agent D,L-camphor-10-sulfonic acid (CSA), externally plasticised with triphenyl phosphate (TPP), and processed from m-cresol (MC) solutions, are also presented.

“…This was due to the discovery of organic synthetic dyes (aniline colors) (trigger T3, Table 4-T3; Fig. 4-T3) in 1856, which induced first an alternative system state, and then around 1900, a regime shift of the PB-CES to "the deceptive calm and a flourishing of bow making" upon the complete replacement of natural dyes (Michaelson 1993).…”

Pau-brasil and string instrument bows telecouple nature, art, and heritage

The wood of the pau-brasil tree (Paubrasilia echinata Lam., formerly Caesalpinia echinata Lam.) is used worldwide as raw material for the construction of high-quality bows for string instruments. Alternative tree species are rarely accepted by professional musicians, or by bow and violin makers. Historical overexploitation of this endemic species in the Brazilian Atlantic Forest biome (Mata Atlântica), a global biodiversity hotpot including UNESCO World Natural Heritage Sites, and illegal trade have caused drastic declines in its natural abundance. Pau-brasil is now classified as an endangered species and listed in Appendix II of the Convention on International Trade in Endangered Species. Traditional bow-making craftsmanship, an intangible cultural heritage, depends heavily on the high-quality pau-brasil wood. This complex situation presents unprecedented cross-continental transdisciplinary challenges. In order to target the protection of this coupled natural/cultural heritage, this work frames and examines the pau-brasil/bow-making cultural-ecological system as a complex telecoupled system linked by cultural ecosystem services provided by the pau-brasil, as well as the relationships and cultural exchanges among key actors. Using historical trajectory analysis, we identify past, present, and potential future trigger events, key drivers, and key system variables that explain the dynamics, feedback, and resilience of this complex multidimensional system. Furthermore, with a cross-scale social and power relations analysis, we examine the level of dependencies and influences of contemporary key actors on the ecosystem services provided by the pau-brasil and their interconnections, in order to ultimately identify their level of disadvantage regarding the pau-brasil. Finally, we discuss the potential of this novel cultural-ecological system approach to (i) interlink science, nature, and art, (ii) reconcile the currently competing protection aims of natural and cultural heritage elements, and (iii) provide future trajectories regarding the resilience and sustainable development of this pau-brasil/bowmaking cultural-ecological system. We advocate for this novel path forward toward sustainable transformation of complex culturalecological systems urgently needed to navigate our increasingly telecoupled world.

“…Aniline is an important precursor for the synthesis of different dyestuff as indo dyes, aniline black ( pernigraline), mauveine or aniline blue. [55][56][57] Then, performance as biocatalyst of the enzyme overproduced in A. oryzae for the synthesis of polyaniline and a naphtol-derived compound as dyes was assessed at relevant industrial conditions at SETAŞ A.S (Turkey), a leader company in chemistry and industrial colour processes. The textile dyeing capacities of the resulting colorants were evaluated using standard industrial tests.…”
