Selective Synthesis of Oxacalix[6]arenes and Mixed Oxacalix[4]arenes

Calixarenesare macrocycles composed of benzene rings meta linked to each other by one carbon atom. These exotic compounds can be used for a variety of purposes including metalleaching for environmental cleanup, surface technology, luminescent probes, nuclear waste treatment, among others. A variety of calixarenesexist, including azacalix[n]arenesthiocalix[n]arenes(where n = the number of benzene rings) and oxacalix[n]arenes; these macrocycles use nitrogen, sulfur and oxygen, respectively, as the atom whichlinks the benzene rings together. My research has focused on synthesizing oxacalix[6]arenes (“hexamer”) in high yield, which is a synthetic challenge because it is generally accepted that oxacalix[n>4]arenes will thermodynamically decompose to the oxacalix[4]arene (“tetramer”); i.e. heating the reaction mixture will yield the tetramer, not the hexamer. To generate the hexamer, “trimer”precursors have been synthesized, in the hopes of facilitating hexamer ring closure.

Ursula C. Schwerin at Commencement Ceremony

Ursula C. Schwerin (right) is pictured in graduation regalia at a commencement ceremony for the New York City Technical College. The date of the ceremony is unknown. Ursula C. Schwerin, a former City Tech student, was president of the College from 1978-1988. She was the first woman to be president of a community college in the CUNY system along with the first woman to be president of a technical college in the U.S. Under Schwerin's tenure, the College made the transition from a two-year to a four-year senior college. and the school was thus renamed New York City Technical College.

Privacy Advocacy in Libraries in the Age of Mass Surveillance

Alison Macrina is the founder and director of the Library Freedom Project, an initiative that aims to make real the promise of intellectual freedom in libraries. The Library Freedom Project trains librarians on the state of global surveillance, privacy rights, and privacy-protecting technology, so that librarians may in turn teach their communities about safeguarding privacy. In 2015, Alison was named one of Library Journal‘s Movers and Shakers. Read more about the Library Freedom Project at libraryfreedomproject.org.
