Ligands which bind receptors giving stable supramolecular systems are of utmost importance in biotechnology and technological applications. Cucurbituril systems (CB[n], n = 5, 6, 7, 8, 10) have recently been studied as efficient supramolecular receptors for molecular recognition in water. The water environment is a challenge when designing suitable ligands, seeing as they are usually small, hydrophobic organic molecules. The best binding interactions with CB[n] can be accomplished by ligands that combine cationic and hydrophobic subunits in their structure, like for example diamondoid compounds.
Photocages (photochemically cleavable protective groups) have wide spectrum of applications in chemistry, biology and medicine, and therefore, they have been intensively investigated recently. The main goal of this project is the design and synthesis of new photocleveable protective groups. Within the project implementation new aniline photocages with improved properties will be prepared and the photochemical reaction mechanisms of deprotection investigated. A series of carboxylic acid and alcohol derivatives protected with new aniline photocages will be prepared. These compounds are anticipated to react in the photochemical reaction of heterolysis, leading to deprotection.
Dynamics of supramolecular systems facilitates control of the photochemical reactivity and opens opportunities for reactions which cannot be conducted by conventional synthetic methods, in the thermal reactions in isotropic solution. The main strategy of the proposed project is to apply different supramolecular systems to control photochemical reactivity.
Photochemistry of polycyclic molecules: From mechanistic studies to new drugs and medicinal applications
Photons are phenomenal reagents which open new opportunities in chemical synthesis that cannot be attained in the chemistry of ground state. The goal of the project was to find new photochemical transformations applicable in organic synthesis, as well as investigation of the photochemical reaction mechanisms. In addition, the aim of the project was to go beyond the state of the art, and ultimately find application of photochemistry in new medical treatments and synthesis of new compounds, potential drug molecules for treating malignant diseases.

Cage compounds are characterized by three-dimensional structures which have defined rigid geometry and as such, they are very useful synthons in organic synthesis, as well as the indispensable substrates for the mechanistic studies. Moreover, the various atomic positions in a cage can serve as branching points where the additional ligating group can be introduced. These substituted derivatives can be used as building blocks in supramolecular chemistry. The first step towards employing cage compounds in the synthesis of more complex molecular systems is the understanding of their reactions.
