Cucurbit[8]uril Assisted Supramolecular Architectures of Carbon Materials for Hydrogels, Photocatalysis and Sensing

Objective

Carbon Materials (CMs: graphene etc.) are known for their light-weight and, excellent mechanical, electrical and thermal properties. However, one of the main challenges for state-of-the-art CM-based composites is the mass manufacture and low-cost production of uniformly distributed composite materials under aqueous conditions to harness these properties for various applications. Moreover, the surface functionalisation of CMs is still a great challenge, attributed to their inert surface and lack of solubility in many solvents including water.
Supramolecular host-guest complexation could be a useful technique to produce uniformly distributed CMs-based supramolecular architectures (SAs). Cucurbit[8]uril (CB[8]) is a macrocyclic host molecule with 8 glycoluril units yielding a barrel-like shape macrocycle. It can accommodate 2 guest molecules simultaneously, typically 1 electron-poor (1st guest) and 1 electron-rich (2nd guest), forming a heteroternary complex. CB[8] creates an aqueous dynamic supramolecular system that can help improve the water solubility of guest molecules.
Thus, the overall aim of this proposal is to develop SAs based upon host-guest heteroternary complexation between CB[8], CMs and matrices. Two entirely different matrix polymers (organic) and metal NPs (mNPs: inorganic) will be considered. Three CMs will be investigated. i) 2D Graphene(GR), ii) 1D Carbon nanofibers (CNFs) and iii) 0D Carbon dots (C-Dots). Following goals of the project will be achieved in the respective work packages: 1) Surface functionalisation of guest molecules onto CMs (fCMs). 2) To obtain Dynamic Hybrid Supramolecular Hydrogels after the host-guest complexation between fCMs, CB[8] and polymers. 3) Supramolecular heteroternary complexes between fCMs, CB[8] and mNPs to form fCMs-mNPs Supraparticles, and their 4) Applications in photocatalysis and Sensing.
Overall, the fundamental investigation of how fCMs will bind to CB[8] and later to polymers or mNPs will be investigated.

Programme(s)

Multi-annual funding programmes that define the EU’s priorities for research and innovation.

Topic(s)

Calls for proposals are divided into topics. A topic defines a specific subject or area for which applicants can submit proposals. The description of a topic comprises its specific scope and the expected impact of the funded project.

Funding Scheme

Funding scheme (or “Type of Action”) inside a programme with common features. It specifies: the scope of what is funded; the reimbursement rate; specific evaluation criteria to qualify for funding; and the use of simplified forms of costs like lump sums.
