RSC Desktop Seminars in Organic 91AV with the Brazilian Chemical Society 2020 are an initiative from the 91AV and the Brazilian Chemical Society to bring cutting-edge research directly to you!
Covid-19 has exposed us to a new reality where the virtual world is much more important than before. In order to keep our students engaged at the frontiers of Organic 91AV, we have organized a weekly webinar series that is a joint collaboration between the 91AV (RSC) and the Organic 91AV Division of the Brazilian Chemical Society (SBQ). It is an alternative way to share work and interact with potential collaborators.
The sections will alternate between Brazilian and international speakers, in some cases with the opportunity for a selected Brazilian early career researcher to engage with the audience by presenting their recent independent career developments.

Benign-by-design methodologies for a more sustainable future
The design of benign and environmentally sound methodologies has been the driving force of scientists in recent years towards more sustainable methodologies. Attractive and innovative protocols that nowadays are even part of industrial ventures including biomass-derived porous carbonaceous materials, designer nanomaterials for catalytic applications and catalytic strategies for biomass/waste conversion into useful materials, chemicals and fuels have been recently developed in our group in recent years. These topics have extensively covered the preparation and design of (nano)materials, biocatalysts and photocatalysts and their utilisation in heterogeneously (bio)(photo)(electro)catalysed processes, flow chemistry as well as in biomass/waste valorisation practices [1 5]. An important research avenue from the group deals with the search for novel and alternative reaction media in Organic Synthesis including mechanochemistry, organocatalysis and photo-redox processes as well as greener catalytic processes in Organic 91AV (flow chemistry) for the synthesis of APIs. In this lecture, we aim to provide an overview of recent efforts from our group in leading the future of global scientists in benign-by-design methodologies for various types systems and key applications in Greener Chemical proceses including the new ?waste-to-pharma? concept.

Covalent Organic Frameworks as Nanoporous Platforms for Enzyme Immobilization.
Sustainability in chemistry heavily relies on heterogeneous catalysis and the development of efficient catalytic systems is a fundamental aspect for the straightforward production of chemicals. Particularly, enzymes are an elegant option to catalyze reactions due to their high activity and selectivity. However, issues such as low stability and poor recyclability prevent the large-scale implementation, and the immobilization of these macromolecules in solid supports is an important tool to circumvent these problems. During the last years, Covalent Organic Frameworks (COFs) emerged as an exciting class of organic nanoporous materials. Due to their pre-designable structure, they can be prepared with distinct physicochemical characteristics, specific pore sizes and tunable functional groups. Because of that, these materials are considered promising supports for the development of heterogeneous catalyst. Herein, in the present webinar recent achievements of our research group related to enzyme immobilization in COFs are presented.
