Abstract: Photoactive compounds are disclosed. The disclosed photoactive compounds include metal complexes with dipyrromethene-based ligands, which can be substituted with a variety of different side chains or groups or can include various fused ring configurations, such as including aromatic or heteroaromatic groups. The metal complexes may include two dipyrromethene-based ligands, which can be the same or different. The photoactive compounds can be used as photoactive materials in organic photovoltaic devices, such as visibly transparent or opaque photovoltaic devices.

Abstract: Embodiments are directed to permitting client devices that connect remotely to an enterprise network to operate in a site-aware manner. In distributed file systems, files may be replicated in multiple places across a network. Embodiments are directed to providing requesting clients referrals (or paths) to replicas of desired information that are accessible by the requesting client with the least overall “cost” to the client and the network. The present systems and methods allow remote client devices to reliably identify a site with their referral requests so that the referring server(s) may provide site-aware referrals in response to the requests.
