Dokonano syntezy ftalocyjaniny cynku(II) podstawionej ugrupowaniami 3-(pentyloksykarbonylo) propoksylowymi i 2-(1,9-dihydro-6H-puryn-6-on-9-ylo)etoksylowymi. Barwnik scharakteryzowano z wykorzystaniem spektrometrii mas, spektroskopii UV-VIS oraz różnych technik NMR.

6-Methylthiopurine was substituted at the N9 position with BrCH₂CH₂OH in HCONMe₂, at 65°C and etherified with 3-nitrophthalonitrile in Me₂SO at 40°C. The phthalonitrile derivative and 3,6-bis[3-(ethoxycarbonyl)propoxy]-1,2-benzenedicarbonitrile were subjected to the macrocyclization in presence of 1,8-diazabicyclo[5.4.0]undec-7-ene and Zn(OAc)2 in n-pentanol at 110°C to yield a green zinc(II) {1,4,8,11,15,18-hexakis-bis[3-(pentoxycarbonyl)propoxy]-22-[1,9-dihydro-6H-purin-6-on-9-yl)ethoxy]phthalocyanine pigment and a known zinc(II){1,4,8,11,15,18,22,25-octakis[(3-pentoxycarbonyl)propoxy]phthalocyanine as a by-product. The purine-phthalocyanine conjugate was characterized by mass spectrometry, UV-VIS spectroscopy and various NMR techniques.

The notion of conformal measures or densities goes back to Patterson’s work [8]. By a theorem of Milnor and Thurston [7] a piecewise monotone and continuous map of the interval is semiconjugate to one with constant slopes. The semiconjugacies can be defined by distribution functions of conformal measures as shown in [2]. In this note we show that for some transformations the conjugacies are estimable functions and can be used to improve estimation procedures, in particular density estimations.

The duality between smoothness and rotundity of functions is studied in a nonlinear abstract framework. Here smoothness is enlarged to subdifferentiability properties and rotundity is formulated by means of approximation properties.

A conjugacy is introduced for the class of starshaped functions from [0, infinity] into [0, infinity], i.e. the class of functions f such that their slope s : t --> f (t)/t is nondecreasing. This class is stable by several operations and plays a key role in the study of uniformly convex and uniformly smooth convex functions and in the geometry of Banach spaces. Here the inversion of the subdifferential as in the Legendre-Fenchel transform is replaced by an inversion device of the slope s which uses the ordering of R.
