vEnturing oN heTERodoped Polycyclic aRomatIc hydrocarbonS to develop smart labEls

Project description

Making smart labels sensitive to oxygen

The smart labels market is growing in Europe driven by technological advances, making it easier to integrate within the packaging industry. Moving beyond the traditional barcode, smart labels can be used by food manufacturers to improve traceability and to convey product information to consumers, ultimately improving food safety. The EU-funded ENTERPRISE project is working on a new type of smart label. It will develop the first O2-sensitive, user-friendly, rapid, flexible and printable label. Specifically, the project will apply multifunctional chromogenic heteroatom-doped polycyclic aromatic hydrocarbons to produce materials that can empower current packaging technology and elevate electrochromic displays to the age of interactivity.

Objective

The scientific goal of ENTERPRISE is to develop and apply multifunctional chromogenic heteroatom-doped polycyclic aromatic hydrocarbons to produce materials that can empower current packaging technology and elevate electrochromic displays to the age of interactivity.
These smart labels can thus provide information to people in an unequivocal and yet appealing way. We plan to produce materials that, through a selective reaction with O2, irreversibly retain an oxidising event and successively communicate it as an irreversible colour change under a human input. To achieve it, we envisage to prepare hybrid O-doped chromogenic polycyclic aromatic hydrocarbons that, in the presence of O2 and light, will act as a photosensitiser producing singlet O2. The reactive O2 will interact with the chromogenic material itself to give endoperoxide species that, under an external stimulus, yield radical species initiating an irreversible coloured polymerisation. Integration of this material into a prototype electrochromic display will result in a label that operates irreversibly after it has been exposed to O2 and reversibly when not exposed to O2. Considering that the leading cause of food-spoilage is related to aerobic oxidations, we expect our results to initiate a series of further technological advancements in the field of labels for smart packaging of food, opening the door to the first O2-sensitive, user-friendly, rapid, flexible and printable label. Through this fellowship, the applicant will enhance her creative and innovative research potential and her multidisciplinary competence of organic materials, with the final goal to become a prime researcher at the interface between fundamental and applied research. This will be made possible by the coordinated effort of a focused and highly motivated young supervising team composed of a leading academic institution and a vibrant enterprise.
