Abstract:

The quenching of the [Ru(bipy)3]2+ by Cu2L2+ was studied and the data were plotted with the Stern-Volmer equation. The plot showed a break and was divided into 2 regions, <0.5 and >0.5 Cu2L2+: [Ru(bipy)3]2+ molar ratio. Quenching above the 0.5 Cu2L2+: [Ru(bipy)3]2+ molar ratio was slower (330 x 10-6 M-1s-1) than the quenching rate reaction below 0.5 ratio (387 x 10-6 M-1s-1). With Cu2L2+ being a dimeric complex the break and differences in the quenching reaction rates can be explained in terms of the stoichiometry. When the Cu2L2+: [Ru(bipy)3]2+ ratio is < 0.5, then each [Ru(bipy)3]2+ can inte

Abstract:

Electron transfer, ET, and proton-coupled electron transfer, PCET, reactions are central to biological reactions involving catalysis, energy conversion and energy storage. The movement of electrons and protons in either a sequential or concerted manner are coupled in a series of elementary reaction steps in respiration and photosynthesis to harvest and convert energy consumed in foodstuffs or by absorption of light into high energy chemi-cal bonds in the form of ATP. These electron transfer processes may be modulated by conformational dynamics within the protein matrix or at the protein-protei

Abstract:

The goal for this research described herein is the development of a series of transition metal based visible light absorbing chromophores that have excited state lifetimes long enough to actively participate in bimolecular photoreactions and display both two photon excited state absorption and reverse saturable absorption properties. With this goal in mind, the preparation and photophysical characterization of a series of metal-organic Ru(II) and Os(II) complexes with relatively long excited state lifetimes is presented. The approach to extend the excited state lifetimes is to make Ru(II) and

Abstract:

Part I: An improved description of the current transient produced by an abrupt change in the rate of rotation of a rotating disk electrode has been obtained by the method of orthogonal collocation. The procedure provides a formula that accurately describes the expected current transient for at least 90% of its duration. If the final rotation rate is chosen to be ca. 58% of the initial rotation rate, the resulting current transient exhibits simple exponential decay, thereby facilitating data analysis. A simple offset in the time scale of the experiment proves effective in compensating for the e

Tese de mestrado, Química (Química) Universidade de Lisboa, Faculdade de Ciências, 2017<br>Cancer is considered one of the leading causes of death worldwide. Therefore, the search for potential anticancer drugs is nowadays a mandatory topic and many research groups focus their interests and efforts in this area. About 50-70 % of all tumors are treated with platinum based compounds (cisplatin, carboplatin and oxaliplatin) but due to several and severe side effects caused by these metallodrugs and to the resistance phenomena (acquired or intrinsic), complexes with metal ions other than platinum,
