The key reason for such a huge interest in these devices is the associated organic heterojunction effect in which opposite free charges are accumulated at the interface making it highly conducting, which can be exploited in producing highly sensitive and faster response kinetics gas sensors. Metal phthalocyanines (MPc) have been extensively studied to fabricate organic heterostructures because of the large possibilities of structural engineering which are correlated with their bulk thin film properties. Accordingly, in this review, we have performed a comprehensive literature survey of the recent researches reported about MPc based organic heterostructures and their application in gas sensors. These heterostructures were used in Organic Field-Effect Transistor and Molecular Semiconductor\u2014Doped Insulator sensing device configurations, in which change in their electrical properties such as field-effect mobility and saturation current in the former and current at a fixed bias in the latter under redox gases exposure were assessed to determine the chemosensing performances. These sensing devices have shown very high sensitivity to redox gases like nitrogen dioxide (NO2), ozone and ammonia (NH3), which monitoring is indispensable for implementing environmental guidelines. Some of these sensors exhibited ultrahigh sensitivity to NH3 demonstrated by a detection limit of 140 ppb and excellent signal stability under variable humidity, making them among the best NH3 sensors.<\/jats:p>","DOI":"10.3390\/s20174700","type":"journal-article","created":{"date-parts":[[2020,8,20]],"date-time":"2020-08-20T09:35:31Z","timestamp":1597916131000},"page":"4700","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":62,"title":["Organic Heterojunction Devices Based on Phthalocyanines: A New Approach to Gas Chemosensing"],"prefix":"10.3390","volume":"20","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4306-9644","authenticated-orcid":false,"given":"Abhishek","family":"Kumar","sequence":"first","affiliation":[{"name":"Institut de Chimie Mol\u00e9culaire de l\u2019Universit\u00e9 de Bourgogne (ICMUB), UMR CNRS 6302, Universit\u00e9 Bourgogne Franche-Comt\u00e9, 9 avenue Alain Savary, 21078 Dijon CEDEX, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rita","family":"Meunier-Prest","sequence":"additional","affiliation":[{"name":"Institut de Chimie Mol\u00e9culaire de l\u2019Universit\u00e9 de Bourgogne (ICMUB), UMR CNRS 6302, Universit\u00e9 Bourgogne Franche-Comt\u00e9, 9 avenue Alain Savary, 21078 Dijon CEDEX, France"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2272-6633","authenticated-orcid":false,"given":"Marcel","family":"Bouvet","sequence":"additional","affiliation":[{"name":"Institut de Chimie Mol\u00e9culaire de l\u2019Universit\u00e9 de Bourgogne (ICMUB), UMR CNRS 6302, Universit\u00e9 Bourgogne Franche-Comt\u00e9, 9 avenue Alain Savary, 21078 Dijon CEDEX, France"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,8,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"788","DOI":"10.1039\/C9QM00716D","article-title":"Recent advances in organic light-emitting diodes: Toward smart lighting and displays","volume":"4","author":"Zou","year":"2020","journal-title":"Mater.
