While the solution‐phase synthesis of directly fused porphyrin tapes has been successfully developed in recent years, the deposition of these promising compounds in thin film form has remained a challenge. In this study, we report the simultaneous synthesis and deposition of conductive directly fused poly(porphyrin) coatings based on a substrate independent and up‐scalable oxidative chemical vapor deposition (oCVD) approach. A particular emphasis is given to the selection and sublimation conditions of the oxidant. The direct fusion of nickel(II) 5,15‐(diphenyl)porphyrin (NiDPP) is successfully achieved using three different oxidants, namely iron(III) chloride (FeCl3), copper(II) chloride (CuCl2) and copper(II) perchlorate hexahydrate (Cu(ClO4)2·6H2O). FeCl3 is demonstrated as the most suitable oxidant, allowing the formation of mainly singly‐fused poly(NiDPP) or conductive mainly doubly or triply‐fused poly(NiDPP) that strongly absorb in the NIR. High‐resolution mass spectrometry evidences the chlorination of the formed compounds as a side reaction. This chlorination can either be considered as a drawback by preventing the formation of large directly fused NiDPP oligomers or as an asset when targeting the formation of fully insoluble directly fused poly(NiDPP) coatings. Overall, the described oCVD approach opened up the possibility to tune the band gap, conductivity, and solubility of directly fused P(NiDPP) coatings.

“…Amines are released when proteins degrade e.g. under bacterial action, which makes amines an indicator of food spoilage [13], and they may be toxic if consumed [14,15,16]. As sensitiser, we used a water insoluble Zinc porphyrin derivative designed for good adhesion on glass, Zinc 5-(4-carboxyphenyl),10,15,20-triphenyl) porphyrin (ZnTPP) [17].…”

When films of zinc 5-(4-carboxyphenyl),10,15,20-triphenyl porphyrin (ZnTPP) are exposed to waterborne amine in pH- neutral or alkaline media, both Q- band and Soret band respond with a change of absorbance due to the donation of amine 'lone pair' electrons to the metalloprophyrin π orbital. However, this is difficult to reveal with a conventional spectrometer even under high amine concentration. We therefore introduce optical fibres coated with ZnTPP into a bespoke 'light balance' evanescent wave absorbance meter [doi:10.1016/j.snb.2016.05.065]. The light balance makes absorbance changes clearly visible under only 5μM aqueous amine, making PVC membranes redundant. We find sensitivity is higher, and limit- of- detection lower, in the Soret band rather than the Q- band, reflecting the stronger Soret band absorbance. Also, we find that sensitivity is higher, and limit- of- detection approximately two times lower, when rough rather than smooth fibres are used. We believe the rough fibre surface leads to enhanced evanescence, and therefore better overlap of the wave propagating in the fibre with the ZnTPP fibre cladding. We find a limit of detection to waterborne amines below 1μM, which compares well to other sensors for waterborne amines [Korent, S.M. et.al. Anal. Bioanal. Chem. 387 (2007) 2863-2870; Algarni, S. A. et.al. Talanta 153 (2016) 107-110]. We therefore recommend 'rough guide' evanescent wave optrodes, in combination with sensitive 'light balance' detector, to succeed membrane- embedding of colorimetric sensitisers such as metalloporphyrines.

Novel, hierarchically nanostructured, star-shaped ZnO (SSZ) microparticles are synthesized by a hydrothermal synthetic route. The SSZ microparticles serve as effective platforms for electrochemical detection of amines in solution. The morphology and structure of the materials are characterized by X-ray diffraction, scanning electron microscopy, transmission electron microscopy, Raman spectroscopy, and UV/Vis spectroscopy. The as-synthesized SSZ microparticles comprise self-assembled hexagonal prisms that possess nanometer and micrometer pores in their structure and on their surfaces-structural features that are conducive to sensing applications. An electrode fabricated by using the hierarchically nanostructured SSZ materials serve as a sensitive electrochemical sensor for detection of low concentrations of ethylenediamine, with a sensitivity of 2.98×10(-2) mA cm(-2) mm(-1) , a detection limit of 2.36×10(-2) mm, and a short response time of 8 s.
