    Ordering, flexibility and frustration in arrays of porphyrin nanorings

    No full text
    The two-dimensional packing of cyclic porphyrin polymers, ‘nanorings’, on a graphite surface shows a rich and complex behaviour due to their internal symmetry and flexibility. Depending on the number of porphyrin groups within the nanoring we observe either a highly ordered hexagonal phase or frustrated packing driven by directional interactions which for some arrangements is combined with the internal deformation of the cyclic polymer. We study nanorings, c-PN, with N = 10 or 12 linked porphyrins which are deposited from solution onto a graphite surface and investigated using scanning probe microscopy. For c-P12 we observe a close-packed hexagonal array in which the porphyrins on neighbouring rings are aligned, but frustration occurs in arrays of c-P10 since close packing and co-alignment of neighbouring groups cannot be simultaneously realised. These observations are in excellent agreement with the computational predictions of the local ordering, stabilisation effects due to deformation, and the intermolecular interactions in the studied aggregates

    Life in lockdown: Living with vision impairment during Covid-19

    No full text
    This report presents findings from research on the effects of Covid-19 on people with vision impairment, based on a survey of 937 respondents. The survey contained closed questions and open free text questions, both of which are analysed in this report. The survey specifically addressed constraints to everyday life activities (work, education, leisure, recreation, etc.), the extent to which these were negotiated and how this impacted wellbeing during Covid-19. Additionally, it considered levels of support from essential services and engagement with social distancing measures. The research was undertaken in collaboration with Guide Dogs. Survey respondents include Guide Dogs service users and affiliates of Guide Dogs and Visionary who have vision impairment or care for someone who does
